The enzymatic hydrolysis of sucrose by the enzyme sucrase will result in the formation of its two monosaccharide components, glucose and fructose, as seen in the model above. The activity of an enzyme is affected by many factors including temperature and pH. Each enzyme has an optimum temperature and pH at which its reaction rate is fastest. The optimum pH range for sucrase activity is 4 - 8.Imagine the pH of the environment in which the hydrolysis of sucrose is to occur has dropped to 2. How will this drop in pH influence point D in the model?A)The enzyme (B) will allow less of the substrate (A) to move into the active site (C). B)More of the substrate (A) will fit into the active site (C), so more products will be produced. C)The substrate (A) will no longer fit into the active site (C) because the enzyme has changed shape. D)There will be no change to the components of point D with a drop in pH; only temperature can denature the enzyme.
b. what gas is the plant producing?
c. what source of energy is the plant using to conduct the process recorded in part a?
Answers
Answer:
a. Photosynthesis
b. Oxygen
c. Light from the lamp
Explanation:
a. The process that is occurring in the plant's cell to produce the gas in the bubble is photosynthesis. The process involves the use of inorganic substances such as carbon dioxide and water in the presence of light to manufacture carbohydrates. Oxygen is evolved in the process. The equation for the process is as below:
b. The gas produced by the plant is oxygen as shown in the equation above.
c. The source of energy the plant is using to conduct the process is the light from the lamp. Light catalyzes the excitation of photosystems, causing the release of electrons that causes the splitting of water.
The clipping of an aquatic plant in water a. Photosynthesis, b. Oxygen, c. Light .
Photosynthesis stands as the pivotal biological mechanism through which plants, algae, and certain bacteria convert light energy into chemical energy, stored in the form of glucose.
This intricate metabolic pathway unfolds within specialized cellular structures called chloroplasts, where pigments like chlorophyll absorb light, initiating a series of reactions that culminate in the synthesis of organic compounds.
(b) Oxygen, a critical byproduct of photosynthesis, is released into the atmosphere.
During the light-dependent reactions in the thylakoid membranes of chloroplasts, water molecules are split, liberating oxygen.
This oxygen release is not only vital for the plant's metabolic processes but also plays a crucial role in maintaining the Earth's atmospheric composition, supporting aerobic respiration for various organisms.
(c) Light serves as the primary energy source for photosynthesis. Photons from sunlight are absorbed by chlorophyll, triggering a cascade of events that convert light energy into chemical energy.
This energy conversion powers the synthesis of adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide phosphate (NADPH), essential for the subsequent synthesis of glucose and other organic molecules.
Collectively, these three components encapsulate the intricate dance of energy transformation, gas production, and biochemical synthesis that sustains plant life and influences the entire ecosystem.
The elegance of photosynthesis lies in its ability to harness the radiant energy of the sun and convert it into life-sustaining resources.

When the spore lands and germinates in the orange, a small tubular extension starts to grow. This new cell will from a strand of hyphae, complete with a nucleus, organelles and cytoplasm. The tube is similar in structure to a straw, but instead of plastic, its firm cell wall or exterior is made of a strong substance called chitin.
The hyphae can now get to work on a piece of fruit, hyphae are crucial to the absorption of nutrients because they can contain a secret weapon: digestive enzymes. When the enzymes are released, they break down food so that its molecules can be easily absorbed. As the hyphae take in their nutrients, they add new cells and extend upward.

The order of bases along a gene determines the structure of a protein (Option b).
- During gene transcription, a specific fragment of DNA called 'gene' is used as template to create a messenger RNA (mRNA).
- Subsequently, the mRNA travels to the ribosome where this sequence is used as a template to create a protein by the mechanisms of translation.
- The linear order of nucleotides in the gene sequence and ultimately the order of triplets of nucleotides (i.e., codons) in mRNA determine the linear order of amino acids in the protein.
In conclusion, the order of bases along a gene determines the structure of a protein (Option b).

Answer: Drug action; drug effects
Explanation:
Drug action can be defined as the combination of the drug with the specific site of the receptor and brings about specific changes at the molecular level of the organism.
The drug effect can be defined as the physiological and biochemical changes that occur at the consequence of action of drug. The effects of the drugs on the body can be observed in the symptoms.
